Two Part 351 Cleveland question..

Ok trying to help a friend of mine out so i've got two questions roled into one..

First is how can you identify a 351C from a 351W just by looking at it and not runnin any codes(the motor is in a Bronco and covered in your normal grit)

second question is if it turns out to be a Cleveland what manual ******'s can we throw behind it without having to break the bank...

it's in a 4X4 78 Bronco with a four speed manual..

I have an early borg-warner T-10 i might be able to lend to him if it will work.. I know the guru's on the Hamb can get this started.. thanks guys..

 

351C,351M,400M has the thermosat housing in the block. 351W is just like 260,289,302. There are a lot of other things, but this is the easiest for me.

 

If it's the original engine in a '78 Bronco it is a 351W or the 351M/400. As was said before if it has a wet intake it's a W. If dry it's a 351M/400. The W takes any ****** that fit the 289/302/351C & W. If it's a 351M/400 it has the same bell as the 429/460 a more limited selection with that bell for a stick.

 

Vs just looking where the upper radiator hose goes? Don't think so.

 

Im running a toploader 4 speed in my 351 C, but your T-10 should work also.

 

hey thanks for th help guys.. no it wasn't the original motor for the bronco.. i was pretty sure broncos didn't come with clevelands in them so i asked him if it was the original motor and he said no..

 

right, stock was 351M or 400, nothing else. These have 7.75" across the top two bolts on the bellhousing. These engines also look big in comparison to the others, but to the untrained eye, that may not work.

To simplify the upper rad. hose, if it goes in horizontally, it's a W, if it goes in vertically, it's a 335 series, 351C/M/400. There are several casting differences between the C and M, but to measure the upper bell bolts is simple enough, or look at the 1 inch raise in the casting by the dist. M's are raised.

2nd part is anything that fits behind a C is the same as 302, 351W, 240/300 6, a**** other lesser knowns. Flexplate balancing will need to be figured out, though.

 

Some people might use that term in connection with fuel injection doesn't mean everybody does. In this case we are talking about weather the intakes have coolant in them. the 351W has coolant & thermostat, the C & M doesn't. The 51-4 Chry Hemis have coolant & thermostat in them, 55 -58 don't. Wet or dry intake, not a terribly difficult concept to follow.

 

thanks again for the info guys but seriously, bulldogmafia and george, it was a simple question that i knew would have a few different answers.. it was certainly no cause for an automotive knowledge **** measuring contest.. any ways back on topic.. if my memory serves me right the upper radiator hose was vertical with a slight tilt to the p***enger side.. does that help at all?

 

A C will have a 2 or 4 in the upper corners of the heads outside of the valve covers, the M doesn't. The C & M thermostat sticks straight up out of the block.

 

If you know what you are looking at it is super easy to tell.

This is what a 351c valve cover looks like:



And this is what the pattern and shape of what a 351w valve cover looks like:

 

Oh,and BTW,as already mentioned,a 78-79 Bronco either came with a 351-M or a 400,and that is it. They never came with a 351-W or 351-C,and by doing so you would also have to swap the bellhousing on the transmission,so it probably has the 351-M in it.

 

Man some of you guys like to get in ******* matches don't you?
Back on topic - Cleavland (and 351/400M) have the thermostat housing bolted to the block itself in front of the manifold. Windsors have it in the manifold.
You can't go by vertical as late 302's and some 351's have a 90 degree thermostat housing that put the hose vertical.
Fuel pump is another good indicator as stated - Vertical bolts, Cleavland or M, Horizontal Windsor.

 

Simple way to tell a 351 Windsor from a 351 Cleveland is just look at the width, Clevelands are way wider than the Windsors!!!-----Don

 

Yeah,but try telling that to someone that probably doesn`t have the 2 motors there to compare.

 

yeah my friend said they had to either change the bell or use an adapter (he couldn't remember which, it was 10 years ago)

 

Heres a 351C 2v out of 72 stang In a 51 F1 Panel

 

You could have a 351 Morfadite also, since it is a '78; still a Clevland style canted valve head. 221-260-289-302W-351W are inline valve heads. Cleavland (and M) valve covers have 8 bolts, Windsor design have 6. If it is a 351M, the 400M crank goes right in for an extra 1/2" stroke. Hope this helps!

 

I'm not much into Fords but, correct me if I'm wrong, the easiest way to tell is that the Cleveland has the timing case built into or onto the block instead of the bolt on ,like the windsors and 302's ?

 

That is another way.

 

Wow....guess you didn`t read all of the above?
